B-Line Eaton series JIC panel enclosure, 6" height, 3" length, 4" width, 12, Hinged cover, 12CHQRC enclosure, Wall mount, Small single door, External

The 12CHQRC enclosure measures 6 inches high, 4 inches wide and 3 inches deep, and it weighs 2.7 lb. That 3 inch depth is the number to check first: it sets how much room you have behind the door for a DIN rail, terminal blocks or a small relay once the back panel is in. Body is 16 gauge carbon steel.

No. NEMA 12 is an indoor rating covering falling dirt, circulating dust, lint, fibers and dripping non-corrosive liquids. It is not a rating for rain, sleet, hose-down or corrosive washdown areas. For an outdoor wall or a wet process area you want a 4 or 4X box instead, and 4X in stainless or non-metallic where there is chemical exposure. Indoor plant floors, machine shops and mechanical rooms are where this carbon steel NEMA 12 box belongs.

Yes. The 12CHQRC carries UL 508A, which is the standard for industrial control panels, so it can house control components in a 508A-built panel. It is made in the US.

The cover is hinged on a continuous piano hinge and held shut by a pull-drawn catch, so it opens like a door and closes with a quick latch rather than screws. That is the difference from a screw-cover box: you get one-handed access for troubleshooting without loose hardware to drop into the machine. Sealing comes from a seamless poured in-place gasket.

JIC-style boxes like the 12CHQRC are supplied with solid walls, so you punch your own conduit openings where you need them and seal them with the correct fittings to keep the NEMA 12 rating. In 16 gauge steel a standard knockout punch handles it cleanly. Use gasketed hubs or sealing locknuts on every penetration.
